.Application led `Yanuary 15, 1913. Serial No. 742,206.

To all whom t may concern Be it know-n that I, FRANK P. Lesson, a citizen of the United States, residing at Plainview, -in 4the county of Pierce, State of Nebraska, have invented certain new and useful Improvements in Tire-Chains; and I do hereby 'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make -and use the same.

This invention relates to tire chains and has for an object 'to provide an extremely simple and inexpensive'tire chain which may be easily applied and removed and when applied will 'positively prevent the wheel skiddingon icy or slippery roadbeds.

With the above'objects yin view the invention consists of certain novel details of constructionv and combination of parts 'hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction Y'within vthe scope of the appended claims.

In the accompanying drawing illustrating 1 is a fragmentary side elevation. Fig. 2 is a fragmentary plan.

sect-ion taken on the line Fig. 4 is a cross section taken 1 -4 Fig. 1. Fig. 5 is .a cross section taken on the line 5- 5 Fig. 1. Fig.

6 is a detail perspective view of the tie member.

3 2, Fig. i. on the line Referring now to the drawing in which like characters of reference designate similar parts, the device is shown to comprise a circular seri s of sheet metal plates 10 around the tread of the adapted to extend 4 tire 11, each plate being oblong in outline of perfoand being formed with a pluralityrations 12 and a projection 13.l Each plate is provided on the side edges vwith centrally disposed curved ears 14. 'Each end of each plate is equipped with a pair of upstanding perforated lugs, the lugs 15 at one end being each provided with single perforationsl, 17 at the opposite end being each provided with a pair of perforations 18 and 18.

For connecting the confronting ends of each two adjacent plates, a yoke 19 has the legs terminally passed through the inner pair of plate and then bent back and passed through the outer pair of the perforations said lugs. A second yoke 20 is passed the lug perforations 18 of the lugs 17 of one 18 of the through the perforations of the adjacent yoke engages with the lugs, 'the legs-0f the yoke 'being termina-lily equipped with `eyes 21 `which encircle the biglit of the first named yoke 19. On each side of the series of plates '10 is arranged a chain ring' comprising ajplurality olf links 22 preferably stamped from sheet metal, vthe confronting ends of adja` cent rings being connected by wire tloops 23. The links are the same in number as the plates 10 and each link is provided on one edge with a perforated lug 24.. A Wire loop 25 is passed through the perforation of this lug and through a perforation inthe corresponding ear '14 of the related plate'lO.

For securing the chain rin-gs to the sides of the `tire and preventing escape of the devicewhen the tire is deflated, a vplurality vof U-shaped members 26 formed of stid wire are placed astride of the felly 27 and are terminally equipped with eyes interlock with corresponding wire loops 23 `of both the chain i;ings.

For detachably securing together the terminal plates of the series o plates 10, one ofthe terminal plates is formed at one end with an upturned flange 29 instead of the usual lugs 17 and near the ends of the flange are formed slots 30. A spring wire yoke. 31 is substituted for the usual yoke 19, this yoke being equipped with terminal hooks 32 which are passed through the slots 30 by forcing the legs of the toward each other, the hooks engaging on the rear side of the flange 29,v when t-he legs are released. A spreader rod 33 is provided terminally with forks 34 which straddle the legs of the yoke near the flange and h 'old I the legs spread apart, thereby preventing accidental withdrawal of the yoke from the flange The spreader rod is centrallyv provided with a perforated lug 35 which is passed through an opening 36 in the flange, 'passed through a cotter pin 37 being then to secure the rod to the flange.v

For detacliably securing together the ter-` links of the chain rings, one of the minal terminal links is equipped with a bar 38 having a hooked extremity 39 which is passed through an opening ll0 in the o-ther terminal Alink, the hook being terminally perforated to receive a Cotter pin 40 which yoke..
